Question

Simplify : `("i"^592 + "i"^590 + "i"^588 + "i"^586 + "i"^584)/("i"^582 + "i"^580 + "i"^578 + "i"^576 + "i"^574)`

Sum

Solution

`("i"^592 + "i"^590 + "i"^588 + "i"^586 + "i"^584)/("i"^582 + "i"^580 + "i"^578 + "i"^576 + "i"^574)`

= `("i"^584 ("i"^8 + "i"^6 + "i"^4 + "i"^2 + 1))/("i"^574 ("i"^8 + "i"^6 + "i"^4 + "i"^2 + 1))`

= `("i"^584)/("i"^574)`

= i10

= (i2)5

= (–1)5

= – 1.
